Prince Edmund Gardener was a member of House Gardener of Highgarden and the heir to Mern IX Gardener, the last King of the Reach.
When his father, King Mern IX, made an alliance with Loren I Lannister, King of the Rock, to join their armies against Aegon the Conqueror, Edmund was given the vanguard. Edmund burned in the Field of Fire alongside his father, brothers, and sons when Aegon and his sisters, Visenya and Rhaenys, unleashed the fury of their dragons.
